ETL Process Design Overview – Draft

For initial data loading, basically, there are 6 steps in the process:

1. Extract raw data

2. Transform raw data

3. Normalize data & Standardize field values

4. Then go back to step 2 using the standardized field values

5. Reconcile and stage entities (reconciliation of keys and referential integrities need to be taken care)

6. Final data loading (this step could be vendor’s ETL tool or just SQL push)
